Methods for making films including a water-soluble polymeric material and a vapor-deposited inorganic coating are disclosed. The method comprises providing a layer of water-soluble polymeric material and vapor depositing an inorganic coating to at least one surface of the layer of water-soluble polymeric material, wherein the inorganic coating comprises a metal oxide. The method further comprises forming a plurality of microfractures extending along the surface of the inorganic coating.

The present invention provides a barrier laminate, comprising an organic layer and an inorganic barrier layer adjacent to the organic layer, characterized in that the organic layer comprises a polymer obtained by polymerizing a polymerizable compound having two or more polymerizable groups per molecule, and has a refractive index of 1.60 or higher, and in that the refractive index of the inorganic barrier layer is 1.60 or higher. The gas barrier film exhibits high barrier properties and transparence.

Films including a water-soluble layer and a vapor-deposited organic coating are disclosed. The films can optionally further include a vapor-deposited inorganic layer. The films exhibit enhanced barrier properties.

A flexible insulation material comprising a flexible porous medium defining a pore volume, and a phase change material (PCM) within the pore volume.

A tubular liner has an open proximal end and a closed-end distal area, and a fabric layer continuously defining an exterior surface of the liner without interruption. A polymeric layer having first and second surfaces is bonded to an interior surface of the fabric layer. A seam is formed by opposed sides of the fabric layer joined together and forming an excess portion directed toward the cavity of the liner. The excess portion is embedded in the polymeric layer.

A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

Films including a water-soluble polymeric material and a vapor-deposited inorganic coating are disclosed. The water-soluble polymeric material may comprise polyvinyl alcohol. The vapor-deposited inorganic coating may include a metal oxide. The vapor-deposited inorganic coating may include a plurality of microfractures. The films may form part of a package and/or a water-soluble unit dose article.
